I am trying to locate LAS points which is within a specific distance (25cm or 50cm) from the 3D points in a feature class. This is exactly what the Locate LAS Points By Proximity tool should do. My problem is just that I get a 999999-error, and I have no clue why.

My input files are a Las Dataset and a 3D point feature class and I have tried a lot of combinations of settings and outputs, but with the same error message every time.

I can only drag-and-drop my point feature class into the tool - if I browse to find it in the windows folder, then it is not visible. Maybe that can be a hint for solving the issue.

Tool inputs (I also tried without changing class codes and calculating statistics but again with error)

Message in geoprocessing result


I got the same error but was able to resolve it by applying the Add Z Information tool to the proximity dataset which added a Z field to the attribute table. Note the proximity dataset must be a Z-enabled feature class.


Try using the tool Make Feature Layer first. There you should be able to create a layer that can be used as input to geoprocessing tools that accepts feature layer as input.

Another option is to use ArcPy, where your code could be something like:

import arcpy
from arcpy import env

env.workspace = 'C:/test'
                                    search_radius="50 Centimeters", 
  • Thanks for the suggestions. I tried the Make Feature Layer, but it results in the same error.. and I am not used to work with ArcPy so I'd rather solve it with the tool if possible.
